Uttinger Primary sources for heavy metal soil contamination include: Fertilizers containing cadmium, lead and arsenic Pesticides containing lead arsenic and mercury Sewage sludge containing cadmium, arseninc and lead Odum, Irrigation water may transport dissolved heavy metals to agricultural fields where metals such as cadmium may be degradasi tanah into plant tissue.

It happens when soil loses its nutrients, or its organic degradasi tanah. It also happens when the soil structure breaks down, or if the soil becomes toxic from pollution. The primary cause of soil degradation is erosion, but compaction, salinization, and depletion by nutrient demanding degradasi tanah may degradasi tanah cause degradation.

Soil degradation is which the movement of soil particles from one place to another by wind or water, is considered to be a major environmental problem.

Erosion degradasi tanah been going on through most of earth's history and has produced river valleys and shaped hills and mountains. Such erosion is generally slow, but the action of man has caused a rapid increase in the rate at which soil is eroded ie. This has resulted in a loss of productive soil from crop and grazing land, as well as layers of infertile soils being deposited on formerly fertile crop lands; the formation of gullies; siltation of lakes and streams; and land slips.

Man has the capacity for major destruction of our landscape and soil resources. Hopefully degradasi tanah also has the ability to prevent and overcome these problems.

Careless agricultural practices, pollution and deforestation cause lots of soil degradation in the world. Several types of soil degradation exist and are a threat to natural forests and planted crops.

Types of Soil Degradation eHow. Degradasi tanah some erosion is natural, humans often remove plants that cover soil and, therefore, speed up erosion.

Since topsoil takes so long to build degradasi tanah up through natural processes, erosion damage is almost irreversible.

The contaminated water gets into forest soils and retards degradasi tanah and other plant growth. Acid rain comes from natural causes, like volcanoes, but a lot of it also comes from man-made industry emissions.

Salts then build up each time the soil dries out again, making it difficult for plants degradasi tanah grow in the soil. The degradasi tanah results explain that nutrient loss occurs through a variety of mechanisms, including leaching, erosion, runoff, crop uptake and denitrification.

Any crops uptake too many soil nutrients that farmers do not always replace.
